Interpretive Summary: When chickens are processed for meat production, they go through a number of washes at the processing plant. In these washes, medicines are added to help clean the chicken before it goes to the grocery store. These medicines differ in their ability to clean the meat from plant to plant. One of these medicines, peracetic acid, was investigated to test its activity in different batches. The results show that this medicine is very stable, and its cleaning activity does not vary between different batches. These results are important for the meat producers and grocery stores because it shows that their products are clean and safe.

Technical Abstract: Peracetic acid (PAA) in poultry processing is not necessarily the same from company to company. Stability is a potential factor in efficacy of the antimicrobial. In order to determine whether or not stability impacted the antimicrobial effects of PAA, one PAA (PeraSafe) was qualitatively compared against two competitor products (Competitor 1 and Competitor 2) at the University of Arkansas Pilot Processing Plant. Ross 708 broilers (42 d) were used for this study. Prior to treatment, 10 birds were sampled post-evisceration. Then, one of four treatment groups per PAA were applied. The birds were dipped in either 400 ppm or 600 ppm PAA, chilled in either 25 ppm or 45 ppm PAA, and then sampled using 400 mL of neutralizing Buffered Petone Water (nBPW). The rinsates were transported to the Center for Food Safety and assessed for total microbiological load with total aerobic plate counts, coliforms, Salmonella (XLD), and Campylobacter (mCCDA). The microbiological plates were incubated as per manufacturer’s directions. There were 10 birds per treatment group in total. Data indicates that all three PAA companies produce effective products.
